BACKGROUND

All homes and businesses receive mail. While some homes and businesses have mailboxes, others have mail slots. Typically, a mail slot is located in a door or a wall of a structure. Because a mail slot can be opened from the outside to allow mail to enter a structure, warm and cold drafts may penetrate the structure through the mail slot and create uncomfortable temperatures within the structure. This problem may further persist even when a mail slot is closed due to poor sealing around the mail slot which allows air to still enter a structure. In addition, insects and other debris may enter a structure through a mail slot and create unsanitary environments in a home or office.

Therefore, there exists a long-felt need in the art for an improved mail slot. There also exists a long-felt need in the art for an insulated mail slot that prevents hot or cold air from entering into a structure through a mail slot. Further, there exists a long-felt need in the art for an insulated mail slot that prevents hot or cold air from entering into a structure through a mail slot, and that also prevents insects or other debris from entering into a structure through a mail slot.
